The plans worked beautifully. My son used them for a fourth grade science/engineering fair project at school. He compared the weight bearing capacity of the three bridges. We were so surprised to see the strength of each bridge. He used bricks for his measurement. The instructions were very easy to read and the templates and photos were a huge help. He was one of the few students to choose an engineering project and surprised us all by getting third place out of about 60 projects in his school and is now headed to the regional competition.

Thank you!
